Why not have a castle 2?
Do you mean the 'team fortress' or the black warrior fortress when you say castle?
1. I think the Team Territory should be split into two areas, I mentioned this before. Right now, the only people who go there are skill noobs like me. A second Combat style territory should be added elsewhere in the wild, maybe styled halfway like the lava maze to trap people (I can dance and escape just about anyone in the skill territory the way it's designed)
The location can be debated but my idea was to swap out things like black demons, fire giants, and otherworldly beings for more skill related kills like chaos druid warriors, giants and Hobgoblins. Lots of Limpwurt, snape grass, gems, herbs. Then expand the skilling nodes a bit. Then in the new area have Black Demons, Fire Giants, Otherworldly Beings, Lesser or greater demons, and maybe baby dragons, or some other higher end NPC with decent drops.
That way we'd have a new area with loot, training, and much more incentive to steal the chest and start a war when it's full of decent loot. Can also move the higher end skilling stuff to the second territory, rune rocks, magic trees, maybe some stalls to steal from.
I believe that would open up a 'king of the hill' style fight for high end loot, instead of the current territory, I hardly ever die and never lose the chest because there just isn't any competition for it. (except that time I had 1100 sharks in the chest)
It would definitely promote more team activity and fighting in those areas with increased risks in the chests.
Note: if you dont like this Idea -1 it please, I am happy at the fort basically whenever I want without losing my collected items, just posting relevant to the thread xD
